Bad Neighbors is a Mega Bloks set.
"It's just a normal day in Bikini Bottom until SpongeBob misfires while testing out his powerful new patty launcher, accidentally breaking the front of Squidward's house! Squidward doesn't like being interrupted in the shower, but that's just what happens when you build the Bad neighbours set by Mega Bloks SpongeBob SquarePants. Put SpongeBob and Squidward's houses right next to each other for all kinds of neighborly nonsense. Move and open up the walls for inside play, or use the working patty launcher for lots of fun messing around! You can collect all the sets to build your own Bikini Bottom world!"
